The hearing originally set for March 4 was adjourned for reasons not specified in electronic court files.

Grindle is charged with three counts of felonious assault, a 10-year felony, stemming from a June 17 incident at Sanford Lake Park.

Prosecutors allege Grindle argued with a 21-year-old Saginaw woman after the younger woman criticized Grindle for leaving several children unattended at the park.

Grindle allegedly responded by driving her 1996 Ford Crown Victoria at the woman and two other Saginaw residents: a 21-year-old woman and a 28-year-old man, investigators claim.

Grindle allegedly slammed the car into a picnic table, launching the man into the air and pinning one woman between the table and another table, detectives have said.

The other woman, the one with whom Grindle argued, ducked behind a concrete wall and avoided injury, authorities have said.

In August, Beale ordered Grindle to undergo a psychiatric evaluation to assess her criminal responsibility and competency for further court proceedings. Two months later, Beale ruled Grindle was psychologically fit to stand trial.
